' PLANTING-MACHINE.

. To all whom it may concern:

improved mechanism for operating the.

valves when the. machine is planting in hills,

which mechanism is so arranged as to com-. pensate for the rise and fall of the furrow openers due to the uneven surfaceofthe ground. f

A further obj ect' of my invention is to provide means for adjusting the furrow openers" and valve operating mechanlsm withrespect to the frame of the machine to adapt the machine for planting on beds asiwill be explained more fully hereinafter.

.The invention consists in the constructionand combination of parts hereinafter described and set forth in the claims. v

In the accompanying drawings Figure 1 is a plan view of a machine embodying'my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a detail of a part of the valve operating mechanism. Fig. l is a detail of the adjusting devices for the furrow openers and valve operating mechanism.

Fig. 5 is also a side elevation showing the parts in a different position from that shown a in Fig. 2. Fig. 6 is adetail in section of one of the. seed distributing wheels. Fig. part of the valve operating 7 is a detail of mechanism.

Like parts are represented by similar characters of reference in the several views. In the said drawings, 1 represents the main frame of the machine which is preferably constructed U-shaped and of. steel.

The usual carrying wheels are represented 3. is a hopper of the usual construction in which are arranged the seed distributing.

devices, the distributing devices which .are preferably employed being those shown in shaft 4, this feed shaft being continuously revolved when the machine is in operation Is acc imation of Letters Patent. Application filed beater 10, 19 10.

from the axle of the. carrying wheels the usual change-of-speed devices being -em ployed to vary the speed of the shaft'in tthe usual way. I

5 -5 represents a series of furrow openers which, may be ofany desired construction thoseshown in the. drawings .being' of the well known sho'emtype, having the usual conduits 6 into which. the seed from the hopper 3 is conveyed through the flexible tubes 7- The drag-bars 8. of these furrow openersare pivotally'connected at their-for? i ward ends ,to' crank arms 9, integrally .formed with sleeves 10 which sleeves are secured to the; transverse shaft 11. This but h'asrounded ends which are'journaled in the depending brackets 12 secured to the mainframe 1.

fiLocatedin the lower end of each conduit 6 of thefurrow openersis a valve 13 pivoted to the walls of the conduit at 14. The rear end of each of these, valvesyis pivotally connected by a rod 15 to a crankarm 16, secured to the transverse shaft 17 oscillat- "shaft 11 is preferably square in cross section ably supported in arms 18 which project H I from thei-sleeves 10 previously described as 1 being" mountedupon the shaft or rod 11. v As"shown in Fig. 1 and also in Fig. 7 the shaft IZ-is provided witha'continuous spline .or key-way- 17 and the sleeves or hubs of the crank arm 16 are provided with keys 16*,

which insures thecrank arm 16 projecting at the same angle; As shown in Fig. 1" these crank armsare retained from lateral moveto one end of this shaft 17 are crank arms 19 and 20 perforatedito receive the end of the rod 21. Theother end of this rod 21 is pivotal-1y connected with one arm 22 of a lever which lever is pivoted. at 23 inc. recess in acasing 24-, which is bolted to the main frame'l. The other arm 25 of this lever projects intotheinterior of the easing into the pathof movement of projections 26 on a wheel 27 connected with the feed shaft 4. Also pivotally connected with thearm. 22 of said lever is a rearwardly 'extendingrod128 slidably supported in 1 a" bracket 29. A spring 30 "coiled about said rod 28 between said bracket 29 and a collar 31 tends to normally hold the lever arm- 25 in the pathof of said drag bars.

scribed and so soon as the projections 26 clear the lever arm 25 the spring 30 will immediately close said valves. This valve operating mechanism is employed when it is desired to plant such seeds as corn and beans in hills. When it is desired to drill the seed, all the valves are held open by a pin 32 which may be inserted through an opening 33 in the rod 28 behind the bracket 29.

The feed shaft 4 has throughout its length a spline or key-way 4:1 by which the various seed distributing wheels are rotatably connected therewith. One of these seed wheels 42 is shown in Fig. 6 and is provided with a series of seed pockets 43. The key 44 on the wheel is located in direct line with one of the pockets. The trip wheel 27 has a key 45 which fits the spline in the feed shaft and this key 45 is located in direct line with one of the projections 26. The number of projections 26 corresponds with the number of pockets in the distributing wheels. By this construction it will be seen that the opening of the valves will be properly timed with the feeding of the seed by the distributing wheels and also facilitate the assembling of the parts. When the feed wheels are changed for wheels with a greater or less number of pockets, the trip wheel will also be changed to correspond.

By having the connecting rods 21 and 15 extended forward and pivotally connected to the rock shaft 17 at a point in close proximity to the pivotal connections of the dragbars 8, it will be seen that the rise and fall of the furrow openers incident to uneven travel will not affect the proper operation of the valve operating mechanism, since the rods 15 in rising and falling with the furrow openers will swing about substantially the same pivotal point.

In certain sections of the country, for planting certain kinds of seed, it is common to construct beds divided by alleys. For planting seed on these beds I have so constructed the machine that the carrying wheel may be adjusted to run in the alleys and the furrow opening devices so adjusted with respect to the carrying wheels, that they will properly plant the seed.

the entire series of furrow openers with respect to the carrying wheels and other parts of the machine.

Secured to one end of the shaft 11 is a.

crank 37 by which the shaft may be rocked upwardly so as to raise the pivotal points This construction maintains the toes of the shoes of the furrows at the same angle with respect to the ground as when in lowered position on level ground. At the same time, owing to the fact that the shaft 17 is connected to the shaft 11, said To aceomplish this I have provided for raising shaft 17 is also swung on the arc of a circle thus raising the pivotal points of the connections therewith of the valve operating rods 15 so as to maintain their pivotal points in the same relation with the pivotal points of the drag bars. hen the machine is thus adjusted the connecting rod 21 is disconnected from the forward end of the crank arm 19 and connected to the rear end of the arm at 20. Also, the connection between the pressure rods 38 and the cranks 39 of the raising and lowering mechanism is also changed so that the springs 40 may exert the same pressure upon the furrow openers in this new position of adjustment as when in the normal position.

Having thus described my invention, I claim:
